NASA releases 'baby picture' of a star that will grow up to be much like our sun

NASA releases image of new star that will be like our sun

Ever wondered what the Sun looked like in its infancy?

A new image from NASA's James Webb Space Telescope has captured what Earth's sun looked like when it was only a few tens of thousands of years old.

The image of Herbig-Haro 211 (HH 211), released by NASA on Sept. 14, shows the outflow of a young star. "An infantile analogue of our Sun," NASA said in a statement.

Located about 1,000 light-years from Earth in the constellation Perseus, HH21 has only about 8% of the Sun's mass. A Class 0 protostar, meaning the nascent star is less than 100,000 years old, "eventually will grow into a star like the Sun," Webb Space Telescope wrote on its website.

The stunning, high-resolution image, with shades of blue and pink erupting from a dark center, shows the luminous region surrounding the newborn star, known as a Herbig-Haro object. As the new star ejects gas jets, these winds collide with neighboring gas and dust, producing the colorful outflow we see in the image.


NASA calls on the American public to help in the hunt for UFOs

Bill Nelson, NASA UFO chief

NASA is calling for a “government-wide approach” to collect data on UFOs, and is even asking the public to use smartphone apps to help identify mysterious aerial craft.

The report released Thursday morning comes a year after NASA formed a group of experts to examine how information about UFOs, which the government officially calls unidentified anomalous phenomena, is collected by the government and private sector. The study is based on unclassified reports and sightings and is separate from a Pentagon effort to collect information on UFOs.

By using sensors from NASA’s Earth-observing satellites and commercial remote-sensing technology, Washington could create “a robust and systematic data acquisition strategy within the whole-of-government framework,” according to the report.

It also added that “artificial intelligence and machine learning are essential tools for identifying rare occurrences.”


'A promising step:' NASA says planet 8.6 times bigger than Earth could support life

NASA says exoplanet could support life

NASA's James Webb Space Telescope has uncovered evidence of a possible ocean world larger than Earth with conditions that have the potential to support life.

The exoplanet known as K2-18 b was first discovered in 2015 more than 120 light-years from Earth during the space agency's K2 mission. But Webb's enhanced technology compared to previous space telescopes recently allowed scientists to more closely examine the star-orbiting planet beyond our solar system.

And what they found was nothing short of remarkable.

Observations in 2019 with Webb's predecessor, the Hubble Space Telescope, previously indicated that the exoplanet — 8.6 times bigger than Earth — could be a "Hycean" world with a hydrogen-rich atmosphere and a surface covered by ocean water. Now, a new investigation with the Webb telescope has revealed traces of carbon-bearing molecules in K2-18 b's atmosphere, including methane and carbon dioxide, NASA said Monday.


How to see a newly-discovered green comet this week, before it vanishes for 400 years

How to see Green Comet Nishimura

A newly-discovered green comet is zipping by Earth and is now visible for the first time in more than 400 years.

Comet Nishimura was discovered by amateur Japanese astronomer Hideo Nishimura on Aug. 11 and named after him.

Nishimura first spotted it by taking long exposure shots using a Canon digital camera and a telephoto lens.

When our solar system first formed, huge amounts of debris were left over. So what we see as a comet is a chunk of dirty ice that remains from that time.

Comets typically stay far away from the sun, frozen and impossible for us to see. But every once in a while, one will come in toward the sun.


4 astronauts return to Earth in SpaceX capsule to wrap up six-month station mission

Astronauts return from Space statation

Four astronauts returned to Earth early Monday after a six-month stay at the International Space Station.

Their SpaceX capsule parachuted into the Atlantic off the Florida coast.

Returning were NASA astronauts Stephen Bowen and Warren “Woody” Hoburg, Russia’s Andrei Fedyaev and the United Arab Emirates’ Sultan al-Neyadi, the first person from the Arab world to spend an extended time in orbit.

Before departing the space station, they said they were craving hot showers, steaming cups of coffee and the ocean air since arriving in March. Their homecoming was delayed a day because of poor weather at the splashdown locations, but in the end, provided a spectacular middle-of-the-night show as the capsule streaked through the sky over Cape Canaveral toward a splashdown near Jacksonville.

The astronauts said it was incredible to be back. “You’ve got a roomful of happy people here,” SpaceX Mission Control radioed.

SpaceX launched their replacements over a week ago.


Blue supermoon photos: See images from around the world

Blue supermoon

The moon appeared to be bigger and brighter than usual, given its close proximity to Earth: just 222,043 miles (357,344 kilometers) or so. The Aug. 1 supermoon was more than 100 miles (160 kilometers) farther away.

But is the moon ever actually blue? According to NASA, on rare occasions, tiny particles floating in the air, such as smoke or dust, can scatter red light waves resulting in a moon that appears blue.

About a quarter of the full moons in a year will be supermoons, but only three percent of full moons are blue moons, according to NASA.

If you missed this week’s blue supermoon, it will be a long wait: The next isn’t until 2037. But another regular supermoon is on the horizon at the end of September, the last one of the year.


Metallic spheres found on Pacific floor are interstellar in origin, Harvard professor finds


Ever since he first learned about the strange meteor falling to Earth, astrophysicist Avi Loeb has been determined to discover whether it was indeed an extraterrestrial artifact that had crashed into the Pacific Ocean.

Now, the professor and theoretical astrophysicist at Harvard University says he and a team of scientists are one step closer to making that determination after they retrieved suspected remnants of the meteor in June off the coast of Papua New Guinea. On Tuesday, Loeb said in a media release that early analysis suggests that those small metallic objects actually are interstellar in origin.

The findings may not yet answer the question of whether the metallic spheres are artificial or natural in origin, but Loeb insists that the team is now confident that what they found is unmatched to any existing alloys in our solar system.
